TCP fixes for 2.2: forget sendmsg OOM, tcp_reset error_report

[Julian Anastasov <ja@xxxxxx>]

        Hello,

        Below are two fixes useful for 2.2.22.

        The first fixes SIGIO issue with tcp_reset, stolen from
2.4 - we should send event on error.

        The second one fixes TCP sendmsg problem on OOM (broken
terminals, etc) - we should forget the old error (ENOMEM) and
not to fail with EFAULT.
